Pour about 1 inch of vegetable oil into a frying pan and heat over medium-high heat to 375°F.
Pour batter into a funnel (blocking the tip of the funnel with your finger) or use a squeeze bottle. Position the funnel over the hot oil and slowly pour the batter in a criss-cross and swirling motion over the oil. Fry for 1–2 minutes or until golden brown.
Remove to a paper towel–lined plate to drain. Repeat with the remaining batter. Serve funnel cakes warm with desired toppings.
